STAGE 1- MECHANICAL FILTRATION Water is pumped Into the filter creating the necessary pressure to begin the mechanical filtration stage. There are three phases in the mechanical filtration stage-coarse, medium-coarse and fine filtration Each phase uses a specially designed foam sponge to effectively remove all sizes of unwanted debris.

STAGE 2- Bl OGICAL FILTRATION The biological filtration stage begins when water reaches the bottom of the filter. This stage uses bio-balls providing a habitat for beneficial bacteria to grow. These bacteria naturally convert harmful ammonia and other wastes into healthy nitrates that fertilize aquatic plants and support a healthy pond environment.

STAGE 3 - UV FILTRATION The final filtering stage uses a low voltage, Ultra - Violet (UV)light located in the middle of your filter. Exposure to the UV light kills algae as the water passes upward through the filter on its way back to your pond.
